Claims.

The present invention relates to certain new. and useful improvements in. printers miter gauges, of which the following is a specification.

In the art of printing, as is well known it is 5 frequently necessary to cut leads, borders, or

slugs of proper lengths, as well as with accurately mitered ends in order to form square borders.

While devices of this character have heretofore been proposed and used, those which performed the work accurately and expeditiously were of more or less complicated construction and, accordingly, were too expensive to be within reach of the average small printing shop.

A primary object of the present invention is the provision of a miter gauge, which is simple in construction, accurate in operation, and which can be manufactured and sold at relatively low cost. A further object of the invention is the provision of a miter gauge, which is of such construction that it can be readily secured in opera tive position on any hand rule and lead outtar, as well as on bench saws.

A still further object of the invention is the provision of a miter gauge having a scale for determining. the lengths of the borders or slugs to be cut and comprising effective slug-holding means so disposed as not to obscure visibility of the scale; 7

With the above objects in View, as well as others that will become obvious during the course of the following disclosure, referencewill be made to the accompanying drawing forming part of the same, and wherein:-

Fig. 1 is a perspective view of a lead cutter having operatively attached thereto a preferred embodiment of my invention;

Fig. 2 is a perspective view of my improved device in a preferred embodiment thereof;

Fig. 3 is a transverse sectional view in a plane indicated by the line 3-3 in Fig. 2;

Fig. 4 is a transverse sectional view in a plane indicated by the line 4l in Fig. l; and

Fig. 5 is a side elevational view of a modified form of my invention.

Referring to the drawing in detail, and where- V with the ends suitably joined, as by welding,

preferably at one of the apices of the triangle.

Detachably secured to the base member II], as byscrews I3, is one leg M of a U -shaped bracket !5, the oppositeleg I6 of which is disposed below the base member It] at a substantial distance for providing a channel for receiving the bed plate B,

as is indicated in Fig. 1.

Threadedly engaged within a tapped aperture l l in the leg I6 is the threaded portion of a thumb screw I8, whereby the base member ill may be rigidly clamped on the bed plate B by turning the thumb screw I 8 upwardly into binding engagement with the bottom of the bed plate 3. when the miter gauge; has been properlyposi tioned thereonrelativeto the cutting knife as indicated in Fig. l. a q 7 While the bracket l5'may be permanently secured to the base member l0 if desired, it is preferably removably secured thereto as above disclosed in order that it may readily be. removed if it should be desired to use the device on a lead cutter having a bed plate of such thickness that the channel in the bracket l5 will not receive it or should it be desired to attach the device on a printers bench saw, which does not have the mitering feature.

Suitably secured to one edge of the inclined member- 12 is a plate l9, which, in the preferred embodiment of the invention, includes lugs 2 and 22 at opposite ends thereof andwhich are interconnected by'a rod 23in spaced relation to an edgeZfl of the plate, which edge extends above. the outer surfaceof the'inclined member 52 for providing, in cooperation with the lugs 2! and 22, an edge guide for the slugs or borders to be mitered.

Loosely supported on the rod' 23 by means of V a sleeve 25 for both pivotal and slidable movement relative to the rod is a block 26, to the bottom of which is suitably secured a slug-engaging rubber pad 21, the sleeve 25 being preferably formed by the intermediate portion of a rectangular metal strip, whose opposite ends are in face-to-face contact and suitably secured 'to the i block 26 and between same and the rubber pad 21.

The inclined member I2 is provided with a scale 28 adjacent the edge thereof opposite the edge to which the plate I9 is secured, and which scale preferably is graduated to designate pica's and half picas for accurately indicating desired lengths of slugs to be mitered.

In operation of the improved miter gauge, it is secured to the bed plate B of a lead cutter in the manner above-described and as is illus trated in Fig. 1, with the apex edge at the junction of the base member II] with the inclined member I2 in proper position with respect to the cutting knife C. A slug is then placed on the inclined work-supporting member I 2 with one edge thereof in contact with the edge guide 24 on the plate l9, whereupon the block 26 is moved axially of the rod 23 to a position depending upon the length of the slug and is then pivotally movedon the rod to bring the rubber pad 2'! into effective gripping contact with the slug to hold the same in accurately fixed position by the left hand of an operator, who, with his right hand, will operate the handle E for forming a miter out on the end of the slug adjacent the knife C.

As is more clearly indicated in Fig. 4, the rod 23 is so disposed that the block 26, when in slugengaging position, extends slightly downwardly at an angle to the surface of the member l2, whereby upon pressure being applied to the block, the rubber pad 2'! will not only exert pressure in a vertical direction on the slug, but a component of the pressure will be exerted in the direction of the edge guide 24, and the slug will be accurately held in position on the surface of the member !2 and on the surface of the edge guide 24.

It is to be particularly noted that the block 26 and scale 28 are so disposed that when pressure is being exerted on the block by the left hand of an operator, the scale will not be obscured from vision, whereby the operator can readily ascertain the length of slug which he desiresto cut.

In Fig. 5 is illustrated a modified embodiment of my invention, wherein the triangular frame 50* is solid and wherein the block 26 is secured to plate 59 by hinges 38, whereby the block will have a pivotal movement only. This arrange ment will be highly satisfactory on fixed length slugs, but when cutting slugs of various lengths, the first form of the invention is preferable, since the block 26 can be moved to most effective gripping positions on the slugs.

When forming the triangular frame solid, as illustrated in Fig. 5, the bracket IE will be L- shaped, having the shorter leg 3| secured to a face of the frame by screws 32. 7

While the hinged connection of the block 26 is illustrated in connection with a solid frame, it may be used equally as well with the form of frame illustrated in Fig. 2, and the form of connection of the block 26 illustrated in Fig. 2 may be used with a solid frame of the form illustrated in Fig. 5.

Having thus explained the nature of the invefition and described an operative manner of constructing and using the same, although without attempting to set forth all of the possible modified forms of construction, what I claim as new herein and desire to secure by Letters Patent is:--

1. A miter gauge comprising a triangular frame having a base and an elongated inclined work-supporting surface, a bracket secured to the base for detachably connecting the frame with a cutting machine and with the lower end of the work-supporting surface adjacent the cutting knife, a scale extending lengthwise of the worksupporting surface adjacent one edge thereof, a plate secured to the frame and projecting above the work-supporting surface adjacent the opposite edge thereof for providing a work edge guide, a rod supported by the plate adjacent the upper edge thereof, and a work-engaging and holding member slidably and pivotally connected withthe rod.

2. A'miter gauge comprising a frame having an inclined work-supporting surface, a plate secured to the frame and projecting above the work-supporting surface for providing a work edge guide, a block pivotally connected with the upper edge of the plate, and a yieldable pad carried by the block for engaging the upper surface of work on the work-supporting surface, the pad when in work-engaging position extending slightly downwardly from the pivotal connection of the block for urging the work into contact with the edge guide.

3. A miter gauge comprising a frame having an inclined work-supporting surface, a rod secured to the frame in parallel relation to the work-supporting surface, and the means pivotally and slidably engaging the rod for engaging and holding work at various positions on the worksupporting surface.

4. A miter gauge comprising a frame having an inclined work-supporting surface, an edge guide adjacent one edge of the work-supporting surface, and a member pivotally connected with the frame above the edge guide for movement toward and from the work-supporting surface and with the said member angularly disposed relative to the work-supporting surface when in engagement therewith for holding work in engagement with the work-supporting surface and the edge guide.

5. A miter gauge comprising a triangular frame having an inclined work-supporting surface, a plate secured to the frame and projecting
